It does not work for me. I removed sc44100s output from the graph and forced 48000 for Jack and Pipewire and still: as soon as I connect sc44100 with the input from qtractor, the playback speed changes. Anyway, I think this is a PipeWire problem, another DAW stumbles over sc44100, too.
PipeWire per default allows only 48000 and claims to resample anything else: https://gitlab.freedesktop.org/pipewire/pipewire/-/wikis/Guide-Rates
